Now that I've had it for a few days, here are my thoughts:
(1) it doesn't remember where you were in a song like Phish OD does, so if I pause in the middle of a 20 minute jam and then come back to it a few minutes later, I have to start at the beginning or find where I was with the little circular thing in the middle that doesn't really work well at all.
(2) it turns itself off sometimes when the phone goes to sleep. I was driving and using it with an aux plug into my car, and I had to wake up my phone every few minutes. Never had this problem with the Phish OD app.
(3) I'm paying $10 a month, and for that, I should have access to the webcasts.
(4) The sound quality is just stellar. As someone who is used to listening to the Phish OD app and am at the mercy of whatever sound quality of aud recording that gets uploaded, it is super refreshing to hear everything so clearly. Hearing the detailed nuances of Mike's bass on the Twist from 10/28 is exactly the type of stuff that makes this worth $10 a month for me.
(5) the 90s catalog is obviously lacking (2 shows from '99? really??).
(6) the "albums" section is great and includes everything.
(7) the fact that it includes so many TAB and Mike shows is a great bonus.
